It's ur donut gasket. It's too small i think. Did the tp come with a gasket?

SilliG

The TP came with a doughnut gasket.

I tried the OEM gasket first it didn't work.

hmmm. Wat kinda TP is it?

I do not want to put the vendors name out there until I have had a chance to contact them first. Not looking to bash anyone just looking to get this fixed

just don't know if there is something wrong with my install process or test pipe fitment at the moment

This is a 70mm test pipe but it said bolts to OEM headers.... Frustrating

Bad angle on this photo of my high flow cat but the flanges look much closer together than yours.

The shop manual calls for replacing (fit new) both "spring bolts" and the gasket when reassembling the exhaust. Gasket goes in with the small end into the cat.

^holy shit the underside of your car Chuck, is so clean I could eat off of it. Love it.

Anyways, I had a similar issue with mine when I installed my Berk. Replaced the gasket and I was good to go.

Yea your test pipe looks a lot closer to the header than mine.

Also clean car man
